ORGANIZATION AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION	NOTE A – ORGANIZATION AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION Organization and Description of Business ArcBest Corporation^™ (the “Company”) is a multibillion-dollar integrated logistics company that leverages technology and a full suite of shipping and logistics solutions to meet customers’ supply chain needs. The Company, which started over a century ago as a local freight hauler, is now a logistics powerhouse with global reach. The Company’s operations are conducted through its two reportable operating segments: Asset-Based, which consists of ABF Freight System, Inc. and certain other subsidiaries (“ABF Freight”), and Asset-Light, which includes MoLo Solutions, LLC (“MoLo”), Panther Premium Logistics^® (“Panther”), and certain other subsidiaries. References to the Company in this Annual Report on Form 10-K are primarily to the Company and its subsidiaries on a consolidated basis. The Asset-Based segment represented approximately 64% of the Company’s 2024 total revenues before other revenues and intercompany eliminations. As of December 2024, approximately 82% of the Asset-Based segment’s employees were covered under a collective bargaining agreement, the ABF National Master Freight Agreement (the “2023 ABF NMFA”), with the International Brotherhood of Teamsters (the “IBT”), which will remain in effect through June 30, 2028. On February 28, 2023, the Company sold FleetNet America, Inc. (“FleetNet”), a wholly owned subsidiary and reportable operating segment of the Company. The sale of FleetNet was a strategic shift for the Company as it exited the fleet roadside assistance and maintenance management business; therefore, the sale was accounted for as discontinued operations. As such, historical results of FleetNet have been excluded from both continuing operations and segment results for all periods presented. For more information on the Company’s discontinued operations, see Note D. Financial Statement Presentation Consolidation: The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation. Segment Information: The Company uses the “management approach” for determining its reportable segment information. The management approach is based on the way management organizes the reportable segments within the Company for making operating decisions and assessing performance. See Note N for further discussion of segment reporting. Use of Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual amounts may differ from those estimates. Reclassifications: For the years ended December 31, 2023 and 2022, certain reclassifications have been made between operating expenses lines of the Asset-Light segment to conform to the current-year presentation (see Note N). There was no impact on Asset-Light operating expenses as a result of these reclassifications. The Company also made reclassifications for the years ended December 31, 2023 and 2022, to conform to the current-year presentation by combining immaterial amounts within the tax reconciliation table and the deferred tax asset components table for December 31, 2023.
